Re: jmx, cruisecontrol + rmi / call method with arg

I would think the person who wrote the MBean you are calling the method on
needs to tell you, or provide you with appropriate documentation. If that's
not possible, you could use MBeanServerConnection.getMBeanInfo() to get the
MBeanInfo object. Then you can use the MBeanInfo  method
MBeanInfo.getOperations() to get the MBeanOperationInfo, which has a method
getParameterInfo() which returns a MBeanParameterInfo that you can use to
determine what you need.

Subject: [Mx4j-user] jmx, cruisecontrol + rmi / call method with arg


Hello,
I use CruiseControl which use MX4J to publish its interface to various
protocols. I have built a working CruiseControl Connector which allows me to
remotely trigger tasks. 

Among the methods that can be invoked there is one  which has a parameter,
namely "buildWithTarget". My problem is how to correctly set the target
parameter.

My call on MBeanServerConnection via RMI
	mbsc.invoke("myProject", "buildWithTarget", params, args);
always fails with the following exception:
at mx4j.server.ReflectionMBeanInvoker.invoke(ReflectionMBeanInvoker.java:61)
[cruiseConrolConnector]         at
mx4j.server.interceptor.InvokerMBeanServerInterceptor.invoke(InvokerMBeanSer
verInterceptor.java:238)
[cruiseConrolConnector]         at
mx4j.server.interceptor.DefaultMBeanServerInterceptor.invoke(DefaultMBeanSer
verInterceptor.java:120)
[cruiseConrolConnector]         at
mx4j.server.interceptor.SecurityMBeanServerInterceptor.invoke(SecurityMBeanS
erverInterceptor.java:84)
[cruiseConrolConnector]         at
mx4j.server.interceptor.DefaultMBeanServerInterceptor.invoke(DefaultMBeanSer
verInterceptor.java:120)
[cruiseConrolConnector]         at
mx4j.server.interceptor.DefaultMBeanServerInterceptor.invoke(DefaultMBeanSer
verInterceptor.java:120)

How do I find out what to pass as params and args?

thanks for help.
